The compartments,2,;-5" and ".7, constitute the after refuge compari ment,,the midshiprefuge compartment andf .the" forward refuge compartment,',respectively. .The bulkheads at the ends of these I compartments areof such construction that I each'refuge compartment is particularly, 6 adapted to Withstand deep" submergenccfl 1 pressure;

Each air .pipe12 is controlled by a valve 13 in the manifold 11 (Fig. 9). The stem let of this 'valve'extends through .a stuffing bOX 15 and is provided, adjacent the manifold, with a hand wheel-ltlsecured there the valve stem 14 and an opening is provided through the superstructure to permit access to the hand wheel .17 by adiver exterior of the 'hull;- In-this manner, the admission of air -tox'the'cpipe 12 may be controlled either exteriorly or interiorly 0f the hull: of the boat.v Themanifold 11 :is also providedwith an airgoutlet nipple #1900 opening into the coinpartmentin which the I manifold is located?

Referring; more particularly to Fig. 5, I preferably provide in each refuge compartment a bank of air flasks 21, which are suitablyconnectedto abranch pipe 22 providedwith a reducing valve 22a 'ofsuitable type and havingconnectionewitha pipe.

By properly. manipulating the valves v air under"pressure'lnaly be supplied from one or more of thebanks ofair flasks-to any se- It is to be particularly noted that the I inon air line 24 is'disp'osed at the lower-portion of the hull 1. I consider this of impor-. tance. in yiew of the fact that. a submarine boat,'in' case of collisiorn'is seldom injured at the lower portion of the hull, any injury which thehull may suffer being usually confined to the port on aboveth'e center line thereof. It is vitalthatjthe air line 24 be 1 protected against injury and I accomplish;

" this by disposing the air line in the manner illustratedfand described. It is also to be particularly noted that the'air pipes 12- are disposed below the centerline of the hull V and, consequently, dangerof'injury to these air pipesis reducedto a minimum; Thisis -in1portant as thesepipes-should remain intact, in caseof collision, .rin order that the tanks and' the compartments of the boat inay. be; blown out to increase the buoyancy thereof sufficientlytoj per nit the boat to rise" to the surface. 7 v I Referring more particularly to Fig.3, I

provide a plurality of test pipes 27 which extend: from each of they refuge compartments and open into the same, each of these pipes 1 being controlled. by a. suitablei'valve 28 therein adjacent itsiop'eir end.v The pipes 27 extend-into the other comparanentst-and tanks of the. boat,vv each: of these pipes being pros; vided with". an .arcuate'; head-L29v 1 7);; 1 shapedato conform tor the curvature" of the 30. extending: fore: and; aft off the hull and dispose'di adj acent thetop ofthe..;tank coinpartment', into which the said; pipe extends.
